D. Calzetti,Robert C. Kennicutt,Luciana Bianchi,D. A. Thilker,Daniel A. Dale,C. W. Engelbracht,Claus Leitherer,Martin Meyer,M. Sosey,Max Mutchler,Michael W. Regan,Michele D. Thornley,L. Armus,George J. Bendo,Samuel Boissier,A. Boselli,Bruce T. Draine,Karl D. Gordon,George Helou,D. J. Hollenbach,L. J. Kewley,B. F. Madore,D. C. Martin,Eric J. Murphy,George Rieke,M. J. Rieke,H. Roussel,Kartik Sheth,J. D. T. Smith,Fabian Walter,B. A. White,S. Yi,Nick Scoville,M. Polletta,D. J. Lindler +34 more
TL;DR: In this article, the authors used far ultraviolet to far infrared images of the nearby galaxy NGC5194, from Spitzer, GALEX, Hubble Space Telescope and ground-based data, to investigate local and global star formation, and the impact of dust extinction in HII-emitting knots.
Journal ArticleDOI

Small,Alexander S. Szalay,Myungkook J. Jee,Sug Whan Kim,Tom A. Barlow,K. Forster,Barry Y. Welsh,Ted K. Wyder +34 more
TL;DR: In this paper, the authors used the GALEX UV photometric data to construct a near-ultraviolet color-magnitude relation (CMR) for the galaxies pre-classified as early-type by SDSS studies.
Journal ArticleDOI
Chemical and Photometric Evolution of Extended Ultraviolet Disks: Optical Spectroscopy of M83 (NGC5236) and NGC4625
A. Gil de Paz,B. F. Madore,S. Boissier,David A. Thilker,Luciana Bianchi,C. Sánchez Contreras,Tom A. Barlow,Tim Conrow,Karl Forster,Peter G. Friedman,D. C. Martin,Patrick Morrissey,Susan G. Neff,R. M. Rich,David Schiminovich,Mark Seibert,Todd Small,Jose Donas,Timothy M. Heckman,Y. W. Lee,B. Milliard,Alexander S. Szalay,Ted K. Wyder,S. Yi +23 more
TL;DR: In this paper, the spectral analysis of 31 Halpha-selected regions in the extended UV (XUV) disks of M83 (NGC5236) and NGC4625 recently discovered by GALEX was performed using IMACS at Las Campanas Observatory 6.5m Magellan I telescope and COSMIC at the Palomar 200-inch telescope.
Journal ArticleDOI
The UV-Optical Color Dependence of Galaxy Clustering in the Local Universe
Yeong-Shang Loh,R. Michael Rich,Sebastien Heinis,Ryan Scranton,Ryan Mallery,Samir Salim,D. Christopher Martin,Ted K. Wyder,Stephane Arnouts,Tom A. Barlow,Karl Forster,Peter G. Friedman,Patrick Morrissey,Susan G. Neff,David Schiminovich,Mark Seibert,Luciana Bianchi,Jose Donas,Timothy M. Heckman,Young-Wook Lee,Barry F. Madore,Bruno Milliard,Alexander S. Szalay,Barry Y. Welsh,S. Yi +24 more
TL;DR: In this article, the authors measure the UV-optical color dependence of galaxy clustering in the local universe, using the clean separation of the red and blue sequences made possible by the NUV-r color-magnitude diagram.
Journal ArticleDOI
